To congratulate the couple on their daughter, NASCAR drivers like Jimmie Johnson, Kyle Busch, Joey Logano, Elliott Sadler and Landon Cassill helped make a video offering the new parents some helpful tips as they start another chapter of their lives.

Although many told the Earnhardts how this is going to be a wonderful adventure for them, they also addressed a very obvious component of having a baby: diapers and the contents of them.

Here's what a handful of them had to offer Dale Jr. and Amy.

On diapers:

Busch: My first breakthrough moment was the time that I saw a soft-serve machine. That was, yeah, that was your welcoming in moment. So if you don't know what it is, don't worry, you'll find out.

Johnson: Early diapers - you know, small people, small little poops. Pretty easy. When you move into solid food, the game changes on a few levels, so be prepared for that.

On parenting in general:

Sadler: You have been training for this your entire life. Remember all those times we had to stay up all night, nobody's going to sleep, we need to see the sun come up? …

Having kids is just like living in a frat house. Everybody's gonna be up all night long. There's no sleeping. There's gonna be a lot of stuff that's gonna get broke, and there's going to be throwing up everywhere.
